The DNA molecule, the program for all life, is based on the golden section. It measures 34 angstroms long by 21 angstroms wide for each full cycle of its double helix spiral. 34 and 21, of course, are numbers in the Fibonacci series and their ratio, 1.6190476 closely approximates phi, 1.6180339. B-DNA has spirals in phi proportions DNA in the cell appears as a … [Read more...]
Fibonacci Numbers and Spirals in Plants
Plants illustrate the Fibonacci series in the numbers and arrangements of petals, leaves, sections and seeds. Fibonacci numbers in plant spirals Plants that are formed in spirals, such as pinecones, pineapples and sunflowers, illustrate Fibonacci numbers. Many plants produce new branches in quantities that are based on Fibonacci numbers. Fibonacci numbers in plant … [Read more...]
The Golden Section in Nature: Animals
There are many examples of the Golden Section or Divine Proportion in nature. Below are just a few: The eye, fins and tail all fall at golden sections of the length of a dolphin's body. The dimensions of the dorsal fin are golden sections (yellow and green). The thickness of the dolphin's tail section corresponds to same golden section of the line from head to tail. The … [Read more...]
Golden Ratios in Body Temperatures
Body temperatures and sterilization points fall near the phi points between freezing and boiling. Body temperatures vary, even within humans. The body temperatures of mammals range from around 97° to over 103° Fahrenheit. Birds have average temperatures of around 105° Fahrenheit. The phi point between the freezing temperature (32° F) and the boiling temperature (212° F) … [Read more...]
Human Heartbeat and Fibonacci Patterns
A peaceful heartbeat is said by some to beat in a Phi rhythm. The prominent parts of an electrocardiogram (ECG or EKG) are the P wave, a deflection caused by the current originating in the atrium; the QRS complex, showing the passage of the electrical activity into the ventricles; and the T wave, as the ventricles reset themselves. The electrocardiograms (ECG or EKG) of human … [Read more...]
Human Growth and Development
Fibonacci numbers define key points in human aging. Fibonacci numbers mark key points in the human aging and development process, as illustrated in the following table, based on insights provided by Norman S. Rose, Ph.D. at his site at http://whizkidz.org: Human Age Development Stage Key … [Read more...]
Human Teeth and the Golden Ratio
Phi is found in the dimensions of the teeth, mouth, lips and even your smile. For several decades, Dr. Eddy Levin of the U.K. has used the concept of phi to design aesthetically pleasing cosmetic and orthodontic corrections in the field of dentistry. Dr. Levin's principles are compulsory study in many American Dental Schools. The images below show several how phi … [Read more...]
Acoustics and the Golden Ratio
The application Phi gives superior results in acoustics. It is believed the Greeks used Golden Ratio to achieve the wonderful sound and "ideal acoustics" that Golden Proportion rooms have. Many cathedrals also use the Golden Section, in part, for the same reason. The Golden Section not only minimizes acoustic resonance, it also imparts a very musical quality to the remaining … [Read more...]
Letters Received
A small sample of some of the letters received. Thanks for the support! Thank you so much for providing a site that has all the information about Phi you could want ... IN ENGLISH!!!!!! It was written in simple terms, which anyone who has had geometry can understand. I am enjoying your site immensely. Congratulations on a very excellent website. I was researching the … [Read more...]
Golden Ratio Relationships in Color
Phi relationships in a color spectrum produce rich, appealing color combinations Michael Semprevivo has introduced a concept called the PhiBar, which applies phi relationships to frequencies, or wavelengths, in the spectrum of visible colors in light. Colors in the spectrum that are related by distances based on phi or the golden section produce very rich and visually … [Read more...]
